The document proposes a new public-private partnership called ARISE that would mobilize investment from sovereign wealth funds and multilateral development banks to fund sustainable infrastructure projects. It identifies needs for improved transportation and power infrastructure. Barriers to investment are noted along with recommendations to launch ARISE at the Rio+20 conference, including committing to a project preparation fund and policy reforms to enable resilient, sustainable infrastructure development. Potential initial partners and illustrative projects involving bus rapid transit and solar power are outlined.
